Ok, it seems to be provisioned, vlan 101 and 102, however, other Entities than 0x5 look strange.
Btw, you can see how DSCP point codes are to be used to map point-code to pbit.

Please dump OMCI log:
flash set OMCI_LOGFILE 3
reboot

and after is it providioned by OLT:

cat /var/tmp/omcilog.par

Remember to restore this after this operation.
flash set OMCI_LOGFILE 0

Ok, so it looks like I-010G-Q is quite old model I have not seen before.
What is chipset inside ?

From https://lafibre.info/sfr-la-fibre/paris-17-photos-dune-installation-sfr-fibre-optique-gpon-sur-un-pm-orange/msg113618/#msg113618, it's a BroadLight BL2348 (very old).
There are also images from the web interface : https://lafibre.info/remplacer-sfr/captures-de-linterface-du-mini-ont-sfr/
Due to its small size for the time, this ONT was quite hot.

cat /var/tmp/omcilog.par

The V2802RH doesn't run Linux, so there is only the RTK shell, and probably no filesystem.
There is probably a way to get the OMCI log, I would have to search in the disassembly.

Hello,

Je dois recevoir mon LEOX LXT-010H-D la semaine prochaine.

J'ai actuellement un ONT Huawei fournit par Orange. J'ai bien sûr relevé son serial et vendor.

N'ayant jamais fais la manip de remplacer mon ONT, j'ai quelques questions (de débutant) à ce sujet.

1. telnet sur l'ip192.168.1.1 login:leox password:leolabs_7
2. les 2 commandes que j'ai prévu d'executer sont :
     - flash set GPON_SN HWTC3XXXXXX
     - flash set PON_VENDOR_ID HWTC
3. dans certains cas, il semble qu'il faille passer la commande :
    - flash set HW_HWVER HWTCXXXX (dans mon cas HWTCA240FA)
    est-ce nécessaire ?

Je dois valider d'autres choses pour vérifier que tout fonctionne ?

Merci d'avance.

You are right about that it is different but look here:
https://elinux.org/OSK
The Angstrom distribution provides a replacement kernel and root file system for the OSK, based on the 2.6 kernel.

So it seems to be modified linux version.
Must be, as some modules used by realtek are deliverd as binaries (like for bosa driver).
There must be some real world under the hood

I don't see the link with this, on this page "OSK" is for "OMAP Starter Kit".

Here it's probably something like "OS Kernel".
I didn't see anything in it which suggests it would be related to Linux, except a few leftover strings like .ko or .so names (but not enough).
The entry point is near the end of the whole image, and there is no rootfs.
Since it's a single binary, this would be a huge GPL violation (but they probably wouldn't care).

In uboot : "Booting kernel from OSK Image".

There are "OSK1FS" partitions for the settings.

In the image, there are strings showing specific "osk" support in the SDK :
 - "Diag shell for osk"
 - "rtkbosa for osk"
 - "oskFatal", "oskError", "oskRechedule"
 - "../../swbase/kernel/SWITCH/osksub.c"
 - "../../swbase/csp/rtl86900/sdk/src/app/diag_rtk/src/parser/cparser_io_osk.c"
 - "../../swbase/csp/rtl86900/sdk/src/app/omci_v1/omci_osk_main.c"
 - "../../swbase/application/feature/rg_func_osk.c"
 - various omci_osk_* function names
 - "/CN/cnsd5/trunk/adsl/branches/osk_multiwan"

The advantage over a Linux system would be the size, the V2802RH only has a 4MB SPI NOR (while other known RTL9601 devices have either 8MB or 16MB).
The image itself it about 2MB, and is 13MB once uncompressed.

Do you have an upgrade image file for this device ?

yes, look your messages

binwalk is blind, so I'am guessing it is encrypted by some xxtea or something.

See how I extracted it : https://lafibre.info/remplacer-bbox/onu-externe-2-5gbe/msg971591/#msg971591.
Binwalk doesn't recognize the lzma compression due to unusual parameters, but 7z and LZMA Utils (old package, lzmp tool on Ubuntu) are able to extract it.

I will check tomorrow from bootloader level if it is possible to boot something in paralell and see what is there on flash.

@Fluor dumped the flash contents with a SPI programmer.
